TC-DH12A Combined Electrical Fire Monitoring Detector 

* The non-polar two buses are connected to the monitoring device to realize the communication and power supply functions at the same time. * The address code is electronical, which can be written in advance by the electronic encoder. The engineering debugging is simple and reliable, which can also be set directly on the machine * The microprocessor monitors the operation and transmits the status of the module to the monitoring device in both normal and alarm modes. * Wire system: Non-polar connection to the signal bus of the monitoring device * Line rated frequency: 50Hz/60Hz * Dimensions: 92mm × 59mm × 110mm With the improvement of economic level, all kinds of life factors in cities are constantly changing, and all kinds of situations with high risks and hidden dangers are constantly increasing. In many places that are not within the scope specified in Code for Fire Protection Design of Buildings, there is also the demand of electrical safety monitoring, smoke m…
